Acceleration Sensor
Product No.: TS2109
Measuring range: -6g~+6g
Resolution: 0.003g
Accuracy: ±0.01g
Introduction:
Acceleration Sensor consists of a square-shaped probe (built-in sensing element) and adapter. They are connected by a light cable. Fix the square-shaped probe on the object to be measured and it will be able to measure the acceleration which point in front of the probe during motion. The sensor is suitable to explore acceleration for 1D rectilinear motion.
The sensing element is silicon capacitive Acceleration Sensor. Weight is designed on the free end of silicon cantilever. Metal electrode are deposited on both side of weight so that a moveable electrode panel is formed. Install it between two fixed electrode panel. When inertia force is applied on the sensor, the movable electrode panel has moved slightly so that capacitance is changed. The circuit sensed the changing of capacitance and change electric field on electrode. The moveable electrode panel is kept at original place by field stress. Thus, it is able to output accurate acceleration value.
Calibration:
TS2109 Acceleration Sensor needs to be calibrated before using. Connect sensor to datalogger. Open SWR iLab. Place the sensor level. Click 'calibration' . Select 'Acceleration Sensor'. Click 'calibrate'. Click 'calibrate' , 'OK', 'OK' and 'exit'.
Usage:
There is a sensing direction for Acceleration Sensor. Be careful of the direction of sensor probe. The acceleration measuring direction is shown in figure.
You can add the weight of object to be measured because of mass of light cable to improve the accuracy.
Fix the square-shaped probe during using because it is only able to sense one direction. Make sure the probe is aiming the same direction as motion.
Typical experiment:
- Explore Newton's law of motion
- Explore centripetal acceleration
- Explore resonance phenomenon
- Explore the simple harmonic motion on vertical direction
- Explore damped vibration
Experimental case:
Explore resonance phenomenon:

Notes:
- The measured acceleration is vector. Be careful with that.
- Zero the sensor before every measuring to ensure the accuracy.
- Minimize the effect from light cable.
